Computer Engineering and Computer Science Double Major

What should I do or take during HS to get ready for the college?

Note: I’m aiming for a good engineering school (Cornell, UCLA, Georgia Tech, etc.)

Also, please mention some good suggestions for schools.

Thank You

Take calculus and physics and computer science, preferably the AP classes. Take the SAT subject tests in Math Level 2 and a science class at the end of your junior year, if that is when you are finishing pre-calculus.
